Describe the issue you are experiencing

In configuration > helpers > new helper.
I select from the list: combine the status of several sensors.
In the new sensor configuration window, until recently, there was an edit box where you could type some letters and, with down key, the entities with that text were displayed. Pressing enter selected that entity and enabled a new text box to enter an additional entity.
Now a button called "select an entity" appears and is completely inaccessible with screen readers. In the edit box that appears when it is clicked, text can be typed but the entities with that text do not appear. It is not possible to add entities with a screen reader.
Now it is not possible to use this function by blind users using screen readers.
The same will happen in other possible places where this type of controls have been changed.
I tested it in Windows 10 Pro with JAWS and NVDA and chrome, firefows, edge.

Describe the behavior you expected

Read succesfully with screnreaders.
